Corrosion resistance of low temperature plasma nitrided X12CrMoWVNbN10-1-1 martensitic stainless steel

Original language description

This paper deals with affecting of corrosion resistance of X12CrMoWVNbN10-1-1 martensitic stainless steel after plasma nitriding. This steel was subjected to plasma nitriding at lower temperature of 400 °C for 15 h in the reverse nitriding atmosphere 1H2:3N2 (l/h), tested and then compared to untreated one. The microstructure and microhardness of the untreated and nitrided stainless steel were evaluated. The anodic potentiodynamic polarization tests in neutral 2.5% NaCl deaerated solution were executed and the corrosion properties of the untreated and plasma nitrided steel samples were evaluated. The results showed a nitride layer, consisting of nitrogen rich diffusion layer but without compound layer on the surface of the plasma nitrided X12CrMoWVNbN10-1-1 stainless steel. The surface hardness of the martensitic stainless steel after plasma nitriding was increased significantly. The corrosion resistance of the X12CrMoWVNbN10-1-1 stainless steel was increased only partially. The pitting was evaluated, and the pitting coefficient was calculated. The plasma nitrided steel showed higher (more positive) corrosion potentials, lower current densities and decreased corrosion rates and pitting during electrochemical corrosion tests compared to not nitrided steel.
